Tylor,
A lot of my books are still packed in boxes from moving so I don't have
much definitive information available. I checked AC43.13 and it doesn't
mention anything about substitution. Actually, the version I have
doesn't mention stainless at all although I know there is an aircraft
approved 316L SS tube.
There are several different alloys used for alum. 3003-0 is used for
low pressure applications (mainly instrument stuff). 5052-0 is medium
pressure (hydraulic, fuel, oil). I think the high pressure apps used
2024-T3 (which is a typical alloy for aircraft structures and skin)
For my two cents, I'd replace aluminum with aluminum. If you're in a
corrosive environment, paint the tubes with zinc chromate.
